Answer: Fatty acids are fats that have acidic carboxyl groups on them. Something like CH3-(CH2)n-COOH Unsaturated fatty acids have double bonds between 1 or more of the carbons in the chain. They are unsaturated with hydrogen, but can be hydrogenated chemically. Fatty acids have many roles, but a very common one is to form the lipids in membranes. In that case two fatty acids are usually joined to phosphate plus some others.
b. eye spot
c. pseudopods
d. food vacuole
1. What type of investment would you recommended to your friend? Why?

Explanation:
A) Nothing, the genetic variation will stay the same.
B) The genetic variation will decrease.
C) The genetic variation will increase.
D) This type of gene transfer is impossible in eukaryotes.
Answer:
The correct answer would be C) The genetic variation will increase.
Horizontal or lateral gene transfer refers to the transmission of genetic material between two different genomes which is distinguished from a transfer of genetic material from parent to the offspring that is, vertical gene transfer.
For example, transformation, transduction, and conjugation result in horizontal gene transfer in bacteria.
It increases genetic variation of the population and plays important role in adaptation as well as evolution.
B. Flowers give greater access to sunlight
C. Flowers help transport water and nutrients
D. Flowers assist plants that live in the water
The advantage of flowering plants is Flowers attract insects that transport gametes.
Because they are often showy and endowed with nectaries, the flowers of angiosperms attract animals, such as small invertebrates, birds and bats. Such living beings, when coming into contact with several flowers of the same species, provide the meeting of pollen grains with female reproductive structures.
Flowers help to maintain air quality. They are natural humidifiers purifying the place and releasing oxygen. They also work as aromatizers by exhaling their fragrances.

b. producers
c. the sun
d. water
Answer:
The correct answer would be c. the sun.
The sun is the ultimate source of energy in any ecosystem.
The solar energy is converted into chemical energy with the help of autotrophs or producers through the process of photosynthesis.
The small portion of this energy is transferred to the next trophic level and by end of 3-4 trophic levels, the entire energy is lost as heat or cellular respiration.
The sun is the ultimate source of energy in most ecosystems. This energy is transformed by producers like plants into a usable form through photosynthesis. Water and plants also have important roles in this process.
In ecosystems, the ultimate source of energy is typically the sun. The energy from the sun is initially harnessed by producers, or autotrophs, such as plants, through the process of photosynthesis. These organisms convert light energy into chemical energy that can be used by other organisms. Water and plants also play crucial roles in ecosystems. Water is necessary for photosynthesis, and plants are vital for converting the sun's energy into a form that other organisms can utilize.
